Title: Fuel control system
Inventor: DONA ROBERT FREDERICK
IPC: F02D45/00
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To provide an engine air-fuel ratio control system capable of maintaining stoichiometric fuel-air ratio, which is unrelated to continuous change of the engine operating state during a change in the fuel mixture ratio. SOLUTION: The fuel control system of an engine 13 having a return-less fuel system 11 and the method thereof uses a fuel mixture sensor 41 which adjusts the target air-fuel ratio to permit a continuous change of the fuel mixture state. The fuel control system and method observes the engine operating state and uses it to follow the shift of a small quantity of fuel from the fuel mixture sensor 41 to the fuel injector 14. This system and method use cells in a stack to express the volume of a small quantity of fuel and the fuel mixture state measured corresponding with that volume.

IPC: H01S5/00
Filed: 1992-03-10
Abstract: PURPOSE:To provide a method of manufacturing a crystal structure of high quality by a method wherein AlGaInP crystal is made to grow on a GaAs substrate or a GaAs buffer layer through the intermediary of a specific InGaP crystal. CONSTITUTION:A GaAs buffer layer 2 is made to grow on a GaAs substrate 1, and an In0.5Ga0.5P buffer layer 3 is grown on the layer 2 so as to decrease a modified layer produced with the temporary fall of the surface of the substrate 1 in temperature due to that the surface of the substrate 1 is deprived of its thermal energy attendant on the thermal decomposition of PH3. Then, an (AlxGa1-x)0.5In0.5P clad layer 4, an In0.5Ga0.5P active layer 5, an (AlxGa1-x)0.5In0.5P clad layer 6, an In0.5Ga0.5P stopping layer 7, a GaAs block layer 9, and a GaAs contact layer 10 are successively grown as designed. By this setup, crystal can be made to grow even at a low temperature of 680-740 deg.C without forming a modified layer on an interface where an (AlxGa1-x)0.5In0.5P clad layer starts to grow.

IPC: H01M8/02
Filed: 1994-02-23
Abstract: PURPOSE:To generate continuous electromotive force effectively by performing the removal of the produced water from near the electrode with good responsiveness. CONSTITUTION:The CPU 62 of an electronic control unit 60 senses excessive leak at the surface of the cathode of a solid highpolymer type fuel cell 10 from the output voltage E sensed by a voltmeter 52 and the impedance Z sensed by an impedance meter 54, and performs accordingly the control to enlarge the degree of opening of a motor-driven valve 34 provided in a bypass piping 30. Associated with the rate of flow in the bypass piping 30 is increased, and the rate of flow of the oxygen gas supplied to the cathode of the fuel cell 10 is increased. When the rate of flow of the oxygen gas is increased to V1, water drops coagulated at and attached to the surface of the cathode 120 of the fuel cell 10 are blown off by the dynamic pressure of the oxygen gas of the rate of flow V1 and passed through a gas exhaust piping 40 to be exhausted to the outside. Thereby thin holes at the surface of the cathode can be prevented from being choked with the water drops.

Title: Power amplifier
Inventor: SUMIDA SHIGEROU
IPC: H03F1/52
Filed: 1979-04-28
Abstract: PURPOSE:To avoid the breakdown of the normal amplifier due to the faulty amplifier, by providing the semiconductor switching element between the base and the emitter of the transistor. CONSTITUTION:In case the output of power amplifier A1 is discontinued owing to the breakdown of driver amplifying circuit 3, the output of another normal amplifier is applied to the secondary winding of transformer 8. As a result, amplifying element 6 has no operation due to the voltage of the primary winding, and then element 7 conducts to form the closed circuit including power source 5. And thus the  large current tries to flow. At this moment, transistor 18 of control part 92 conducts  to form the closed circuit including power source 5, and thus the base current of  element 7 is controlled. Element 6 also features the same function to reduce the  power consumption at faulty amplifier A1, and as a result the reduced power consumption does not cause the overload of the normal amplifier at all. If elements 6  and 7 have the short circuit, fuses F2 and F3 are disconnected to cut off the adverse  driving signal. In such constitution, plural number of amplifiers can be connected  in parallel to obtain the increment of the output.

Title: System linkage system
Inventor: HIGASA HIROMASA
IPC: G05F1/00
Filed: 1990-03-02
Abstract: PURPOSE:To cancel the linkage between an electric power system and power converter by only positively feeding back the frequency component of a specific frequency band to the frequency controlling loop of an inverter. CONSTITUTION:When a switch 6 is opened, frequency fluctuation is produced by cogeneration 21. Only the fluctuating frequency component extracted by means of a frequency detector 25 and bandpass filter 26 is sent to a dead zone circuit 24 and the output of the circuit 24 is supplied to a multiplier through another multiplier 29 after amplification by an amplifier 28. The frequency fluctuation of an inverter 12 is caused by the natural frequency fluctuation of the cogeneration 21 and accelerates the frequency fluctuation on a load side. The fluctuation of the frequency outputted by the inverter 12 increases due to positive feedback. When the frequency exceeds the level of a specific- frequency value generator 19, a switch 11 is opened by a frequency abnormality detecting signal from a frequency abnormality detection circuit 18. Therefore, a power converter 10 can be released from an electric power system 7.

Abstract: PROBLEM TO BE SOLVED: To provide an information transmission reception method in which a task of realizing a communication channel is much simplified by increasing a compression coefficient by several orders of magnitude in the method using a UHF as a carrier of an information signal.

A delay circuit 3-1 delays one of the signals outputted from the 2-branch device 2 by a time T. A multiplier 4-1 multiplies the information signal outputted from an information signal generator 5 with a signal from the delay circuit 3-1 to provide an output of a transmission information signal. The transmission information signal is synthesized with a support signal being a signal outputted from a 2nd output terminal of the 2-branch device 2 at an adder/amplifier 6, which produces the transmission signal and amplifies the transmission signal at a designated amplification factor to attain a desired output.

Title: On-chip multiprocessor system
IPC: G06F15/16
Filed: 1992-03-11
Abstract: PURPOSE:To reduce electric power in accordance with a load in a multiprocessor system sharing a main storage. CONSTITUTION:At the time of judging that a load is lower than a fixed level, a processor 101 transfers mts own process to the other processor 111 and then controls a device 103 for interrupting its own clock to stop a clock 104. Thereby power consumption can be reduced by said clock stop. In addition, execution environments for all processes can be continuously effectively held. Since a clock terminal 121 is shared by both the processors when the processors are integrated on the same semiconductor chip 100, a time difference between clocks can be reduced.
